Does Ankyloglossia Surgery Promote Normal Facial Development? A Systematic Review.

Ankyloglossia is a congenital, abnormally short, thickened, or tight lingual frenulum that restricts tongue mobility, which may impair the development of the lower face morphology, namely the occlusion and skeleton. The aim of this study was to evaluate whether and how the lingual frenotomy benefits the occlusion and lower face skeleton development. The authors, independently and in duplication, performed searches of PubMed, Cochrane Library, Medline, Web of Science, and Embase, introducing the following keywords: tongue tie, ankyloglossia, and short lingual frenum/frenulum, combined with malocclusion, lower face skeleton, and hyoid bone.

Changes in the Mandible Following Rapid Maxillary Expansion in Children with Class II Malocclusion: A Systematic Review.

Objective: The aim of this systematic review was to determine whether rapid maxillary expansion (RME) allows favorable changes in the mandible during the treatment of class II malocclusion before the growth spurt.

Methods: A search of Pubmed/Medline, the Science Direct, and the Google Scholar database was performed. The keywords used were: orthodontics, rapid maxillary expansion, class II, and growing patients.
